To all whom t mag/concern.'

Be it known that l, ARNosr darrovsiim a citizen of the United States of America,

' residing at the borough of Brooklyn, county l of Kings, city and State of New York, have invented certain new and useful lmprovements in Pocket Flash-Lights, of which the following is a full, clear, and exact description.

This invention relates to improvements in pocket tlash lights theobject being to provide a lamp of such a construction as to present aunique appearance aswell as to f a spring 8 which acts and 16 through which possess the advantages which will beset forth.

l will now proceed to describe my invention in detail, the novel features of which will be pointed out in the claims, reference being had to the accompanying 'drawing wherein,

Figuregl is a side view of the lamp,

'.Fig. 2 is a vertical central section partly in elevation, and` l Fig. 3 a fragmentary detail view of the switch.

y improved lamp consists'o'fa casing 4 reduced at its lower end 5 which is threaded at 6 to receive an elongated cap 7 containing to force the battery 9 longitudinally ofthe casing to cause the pole 10 to contact with the lamp 1l in the usual manner.` The spring 8, as usual contacts with the zinc of. the battery 9 the circuit being through the spring, cap 7, casing Z1, switch 12, reflector 13', 'which' carries the lamp 11,thence back to the battery. The reflector 13 is kept out of contact with the casing4 by a bushing 14 of insulating material. As'the casing 4: is made somewhat larger than the battery 9, ll provide rings 15 from the bottom of the casing when cap 7 is removed. The rings 15 and 1G prevent `the battery `from lashing around in the casing. The internal diameter of the cap 7 is but little more than the diameter of the battery 9.- Thence it is kept'from lashing at its lower end. Y

The switch 12 consists of a dat strip of metal secured toa button 17 having clips 1.8

*secured to the opposite the battery is slipped [dpecicaten ci ,mettere lliatent.

which pass through a slot 19 in the casing l and engage the switch 12. rlhe only insulated portion of the battery is the upper end at which point the bushing 14 is located.

When the button 17 is pushed toward the 55 lamp the switch 12 will Contact with the I reflector 13 and the circuit will be complete. By making the casing el as above set forth, l am able to do away with insulation to protect the switch as the switch is kept out of Contact with the battery by the spacing rings 15 and 16. The switch strip 12 is the only strip employedand ll do not employ a strip connecting the spring 8 and switch 12 e as isusual in pocket flash lamps. The switch proximately fit the adjacent end of the battery, an elongated cap removably secured to the reduced end of the casing, a spring car.

ried by the cap bearing against thel battery,

and a slidable switch carried by the casing.

2. In a device `as described, in combina a battery disposed concenthe lower portion of said tion, a casing, trically therein,

casing being reduced, a cylindrical tapering cap having its larger end vremovably vsecured to the reduced portion of said casing, one end of said battery being embraced by the reduced portion of saidcasing, a lamp and a spring wedged tapering cap and engaging the adjacent end of said battery to force its opposite endy to electrically engage said lamp.
